eCTA Hot-Wire Bridge
The eCTA is a full featured hot-wire bridge for the dynamic measurement of flow velocities in air. The calibrated velocity range in air reaches up to 50 m/s, higher velocities are possible. Due to the measurement principle the device is especially suited for small flow velocities. The application with different gases is in general possible but requires a special calibration.
The eCTA is designed to operate hot-wire probes of the series HWP1 0/xx, therefore no adjustments need to be made. The eCTA is conceived to work in combination with the data acquisition systems sDAQ and 4CTA.
